Here is the recipe for Fossil Eggs if you want to make them at home. At school we used a cup of Plaster of Paris to make them set extra hard, but you may not have that to use at home.
You will need:
- 1 1/4 cups dirt
- 1 1/4 cups of flour
- 3/4 cups salt
- 1/2 cup sand
- Plastic Dinosaurs
How to make dinosaur eggs:
- Mix together dirt, flour, salt and sand.
- Slowly stir in water to create a dough, clay-like texture.
- Mould the dough around one of the plastic dinosaurs.
- Let the eggs dry thoroughly. This may take all day or several days depending on the weather.
